Relatively new motor, new heater core, new water pump, new thermostat(x3). New blend doors (operational i checked) head gaskets replaced and heads milled, hoses seem to get hot, upper hose on core from to p of engine seems to be hotter than the lower return to radiator. temp gauge never goes above 70-80 ish was not working so i installed an aftermarket gauge and the increments are not that well designated... ive done everything i can think of. and spent way too much money. never had this issue until last winter, this truck used to have really good heat, last year and this year wearing snow pants to and from work cause its - 30- -40° below here in AK Sux.

If the O2.sensor is bad how would I know

the leak was coming from under tourq convertor dust cover.its a 74 Chevy pick up 4x4 350 Auto Trans. it was OK the day before. "Question" would front seal just go out! like that? its winter now, and just too damn COLD! to do the work! but, if you need it.It has to be Done.

the heating system does not blend or just defrost or floor. It mainly blows out of the panel vents

I keep getting this code only problem I seem to have is when its damp outside and Im low on gas it acts like it has a miss

With key on , no power to fuel pump. Relay has steady power but no prime power. Security light is on steady all the time

Engine immediately trips check engine light
Both sensors were replaced
New vacuum hose on map sensor as well
When it first starts it barely runs then a few seconds later settles into so so idle semi rough idle

Acts like chocked and drinks gas

It starts but runs sluggish, the valves are rattling, and a loss of power on acceleration. What would cause this to happen. It's a 4.3 liter engine in a 1991 Chevrolet Cheyenne 1500.

I have a,severe oil leak. It's leaking where the oil filter screws in. Can you tell me what that part is?

I had somone check it and tole me it is not good because he conected a tester and it beep by putting

same as what i said

Replaced fuel filter and pump

regulator.but no guel at check valve

It turns over, but won't crank. The distributor, cap, rotor, plugs, wires, are new. I changed the coil and it started in my driveway and seemed ok, but when I went for a test drive it stalled down the road and wouldn't start again.

The noise is coming from the right side of the engine, and only happens when I accelerate.

A month ago I changed the fluid and filter in my truck, and now it slips while driving it.

My pickup drives like my brakes are locked. And a mechanic told me that my pedals are very low. This has been a problem for the past two years.

even after buffing head light they are still just not bright enough not to hit deer out in the country

i have replaced everything but the wiring from the wire harness and sometimes it works some times it doesn't some times the break or running light will work and the blinker wont some times the running light works and break and blinker don't it is never consistent.

This happens any time the trans switches gears and sounds like it is coming from the rear end area

brakes work fine

It starts fine. It idles ruff. When you try to rev it up,...it's hard to do. It sounds like the fuel is being restricted. You can't get the RPMs to climb. If you keep trying the engine sounds like it wants to die out. The Oil is clean with no water.

problem happened after pulling engine to replace freeze plugs

what do I do

I'm on at least the 4th fuel pump since the truck was new, the last 3 according to the mechanic and my testing had a leaking check valve. I've found inline valves for around $10 which sure beats $150-$300 for a new pump not counting the work involved but need to know the size. THANKS

It just started doing this. I have to start the truck in neutral, because its not reading that it's in park. What is the most likely repair?

I have a 94 Chevy Silverado Z71 and while driving my truck will stop running for about a second then come back to life but sometimes it wont. it also tends to stall a lot when trying to leave a stop sign or a light. We have changed the fuel pump, fuel filter, cleaned all electrical grounds, throttle positioning sensor, spark plugs and wires are fine, and changed O2 sensor. Anyone know what it could be?

New compressor and recharged worked great for 2days ,then it acted like it lost all charge but reads 80 lbs on low side,turn on it go to 0

I have changed wheel cylinders on both side. It is pulling to the left going down the road without applying the brakes left wheel seems to lock up I have replaced the wheel bearings put new brakes on both sides but not help the problem. Someone said it might be the wheel speed sensor or the ABS mod.
